New Course: Learn How to Identify Herbicide Damage

Published on: October 4, 2021

 New online course on diagnosing herbicide injury now available

—Petr Kosina, UC Statewide IPM Program

 

A brand-new online course on Diagnosing Herbicide Injury focusing on how an herbicide injury situation can arise, what information can help diagnose symptoms during field investigations, and what tools are available to you, is now available from the UC Statewide Integrated Pest Management program (UC IPM).

When unexplained damage is noticed on a crop or other non-weed plant, herbicides are often a primary suspect. That is no surprise because herbicides are very powerful and effective tools used to control weedy plants in a wide variety of locations. However, symptoms of many other plant stresses, such as diseases and nutrient deficiencies or toxicities, can closely resemble the injury symptoms caused by herbicides. Economic implications of herbicide damage can vary–in some cases visible injury may have very little direct economic effect while in others, even slight herbicide symptoms can affect the marketability of affected plants. In addition, the presence of an unregistered herbicide on non-target crops can result in illegal residues which could have both safety and legal consequences.

 

The new online course was developed by Dr. Brad Hanson and Dr. Kassim Al-Khatib from the Department of Plant Sciences at UC Davis, and UC IPM instructional designers. If you are a grower, pest control adviser, or pesticide applicator, then this course is a great opportunity to learn about how to approach crop injury investigation when herbicide is suspected cause. You will learn how herbicides injure plants, how long herbicide symptoms may last and factors that may influence the time that herbicide injury symptoms are visible, possible scenarios of herbicide exposure based on uniform and variable injury patterns observed in the field, how to prepare samples for the laboratory analysis and more. 

The course content is free to anyone who wishes to view it. For those requiring a certificate of completion and continuing education units (CEUs), the regular cost is $30, but we are offering a reduced price of $15 through October 31, 2021. Diagnosing Herbicide Injury course has been approved by the California Department of Pesticide Regulation (DPR) for 1.5 continuing education units (CEU) of Other, Certified Crop Advisor (CCA) for 1.5 units (IPM), and the Arizona Department of Agriculture for 1.0 Credit.

 

If you are a DPR license or certificate holder with a last name beginning with letters M through Z, then this will be your year to renew. Now is a good time to check out the other UC IPM online training courses offered. All are 50% off the regular price through October 31st. DPR strongly suggests returning renewal packets back to them by October so that your license or certificate can be renewed before it expires. Many of our courses are accredited by DPR for continuing education hours and also by the California Structural Pest Control Board (SPCB), Certified Crop Advisor (CCA), the Western Chapter of the International Society of Arboriculture (WCISA), and the Arizona Department of Agriculture.

February Is About Safe Pesticide Use - Free Courses
Tammy Majcherek
Published on: February 17, 2022

To raise awareness of pesticide safety practices, February is celebrated as National Safety Education Month. This year the University of California Statewide Integrated Pest Management Program offers help to refresh your knowledge about safe and effective pesticide use. Two frequently sought-after online courses focused on proper pesticide use to avoid illegal residues and proper selection, use, and removal of personal protective equipment are offered for free during the month of February. Use code safety100 at checkout to get your continuing education units (CEU) for free.

 

Pesticides are among the most regulated chemicals in the country. In the United States, the Environmental Protection Agency (EPA) regulates the use of pesticides. All pesticides must be registered with the EPA, and the agency requires a battery of scientific tests to determine the potential risk to humans and the environment.

Best practices for using pesticides safely start with reading the label before each pesticide application. How will reading the label help you? Pesticide labels answer most of the basic questions you need to know about the product, its safe application and handling. Always make applications in strict accordance with all label instructions. Following label instructions will ensure safe, effective, and cost-effective use of the pesticide. Apart from the label, it is important to know what your state regulations are because some state regulations that also have to be observed are not written into the label. Note that not all pesticides approved by the EPA and available for purchase in the United States can be used in California. California is one of the few states that have more strict pesticide regulations for certain pesticides than what is required by the EPA. Even if you have used a given pesticide in the past, make sure you have an up-to-date label, as EPA may occasionally change labels. To learn more about pesticide labels and how to extract information relevant to the specific setting and situation in order to apply pesticides safely, enroll in the online course Proper Pesticide Use to Avoid Illegal Residues. Pest management professionals will earn 2.0 hours of Laws & Regs CEUs.

Because pesticides have the potential to cause injury or illness to anyone working with them, it is important to wear personal protective equipment, or PPE, to reduce a person's exposure to pesticides. PPE includes clothing and certain devices worn to protect the human body from contact with pesticides or pesticide residues. Regular clothing is not considered PPE even though some pesticide labels may indicate that these specific items of regular work clothes can be worn during certain activities. All employees who handle pesticides in California are legally required to wear PPE. They must follow all PPE instructions on the pesticide label and follow all California laws and regulations. To learn how to select the proper PPE, use it, remove it, and dispose of it or clean and store it before, during, and after each incidence of pesticide handling and application, enroll in the online course Proper Selection, Use, and Removal of Personal Protective Equipment (PPE). Pest management professionals will earn 1.5 hours of Laws & Regs CEUs.
